Well, here it is. The bolt is NOT ramped and does require a 9mm specific hammer. What I am kicking myself over is I should have gotten the whole kit. Using a RRA 9mm hammer and RRA heavy buffer, simple enough to put in but, the original LPK is all polymer parts (except pins and springs). Metal hammer + polymer disconnector = replace all polymer with metal parts. I have no idea how it shoots. YET! The mag block is by promag, (I went cheap and got cheap), PSA metal mags fit too loose, gonna try Promag's see if they are any better fitting. I do have it all together, and it looks and feels real good. Just have to fix the disconnector, and the mag fit. Should be range ready after christmas.
I know kinda wordy, Might be in the wrong section for all that.
